2017 Enviorthon Team: Helen Bosch, Fiona Powers, Bridget Powers, Hayden Tillinger, Rob Tabaracci, Madi Ulmquist, Caleb Noble, Cody Tofflemire, Eliot Pryor, Emily Burke and Kip Giddings
2016 Envirothon Team! Ashleigh Crum, Rob Tabaracci, Sarah Mad Plume, Kip Giddings, Dexter Clark
The Envirothon Team is made up of 5 members and CHS can have 2 teams. We like to also have 2 alternates. We meet weekly at lunchtime in Room 232 every Wednesday. On the third week of April, we travel to Lewistown for the state competition. Students are tested on their knowledge in five topic areas: soils and land use; aquatic ecology; forestry; wildlife; and a current environmental issue that changes each year. Through the program, students develop an understanding of effective teamwork, resource management and ecology. At the same time, they gain valuable exposure to a range of disciplines while exploring possible career paths.
National Envirothon Competition
Study materials for Wildlife, Soils, Forestry and Aquatics and the Current Issue
Western rangelands include prairies and grasslands, sagebrush steppes, and
woodland areas. Rangelands comprise more than 40% of the total
productive land base in the western U.S. Rangelands sustain an abundance
of forage for both livestock and wildlife, as well as providing aesthetic beauty
enjoyed by many. Rangeland resources are a critically important ecosystem
component of the western US landscape and are a vital economic factor for
many agricultural producers.
Western rangeland management objectives include grazing, timber harvest,
recreational uses (including hiking, camping, fishing, hunting, etc.) and
mining. Western rangelands are diverse and rich in natural resources and
provide an essential fresh water source for all of the western U.S. Public
land managers and agriculturalists work to protect these resources to ensure
their sustainability for generations to come.
Envirothon Teams will learn about the importance of western rangelands, and
the need for balance in management planning. Livestock producers are an
important economic driver in the western US, sustainably utilizing the
rangelands to maintain a living and produce a valued product. As good
stewards of the land, most livestock producers work to protect natural
resources, including sage grouse habitat and prevent catastrophic
wildfire. Differences of opinion on management strategies of western public
rangelands have resulted in escalating friction between Non- Government
Organizations (NGO’s), political representatives, federal land managers, and
permittees. Disputes arising from this diversity of opinion often end up in the
judicial system, through expensive and lengthy litigation. This process does
not lead to timely and effective land management decisions, nor does it
foster good working relationships between stakeholders. Federal land
managers are placed in a difficult position, charged with consideration of
multiple and often conflicting views, and are often seen as capitulating to one
or other groups with extreme views. It is important that public rangelands be
managed in consideration of all environmental, social and economic
objectives, so as to provide the widest possible range of benefits. A key
factor in developing the best possible management strategy is honest and
effective communication between stakeholders.
Envirothon teams will learn how Best Management Practices are used to
protect western rangelands, improve grazing management schemes, promote
pest management, reduce uncontrolled wildfires, and improve habitat for
sage grouse and other wildlife. Information provided and site visits will
demonstrate the importance of finding the optimum balance between natural
resource protection and agricultural use on western public rangelands.

- All soils are derived from underlying parent materials which are affected by geological processes.
- Water quality is directly related to sediment types. Sediment types affect the impact of pollution on water quality . Groundwater moves through a clay layer at a rate as low as one inch per two years, while water moving through beach sand can travel up to five feet per day. Groundwater pollution in the former situation is much slower to recover. Although the polluted plume does not spread quickly, the clay makes it impossible to pump out.
- Soil stewardship became a national issue in the 1930’s with the Dust Bowl. Erosion problems began in colonial times. Farmers did not adapt European farming methods to the different climate in North America where water events occur more frequently as storms producing greater volumes of precipitation during shorter time intervals. Farmers also grew the same cash crop every year until the soil was depleted. Then they moved on and farmed elsewhere due to the cheapness of land. Later, more industrial-sized equipment such as the tractor was developed, enhancing the depletion of the soil layer. By the late 1940’s nearly all privately owned land in the Nation was part of a conservation district designed to promote soil stewardship.
- Soil erosion continues to be a serious problem in Montana. Wind and water erosion are occurring on Montana cropland at a rate of 132 million tons per year.

- Silviculture involving the explanation of the difference between clear-cut harvest and clear-cut silvicultural system, explain the difference between a thinning, diameter-limit cut and the single-tree selection system, understanding and explaining the difference between even-aged and uneven-aged management systems, listing probable reasons why a logger and a forester might select different trees for harvest, defining the goals of thinning in comparison to the goals of final harvest, outlining the goals and approaches used by the major silvicultural systems to insure stand regeneration after harvest, and be able to list at least five best management practices used to control flow of water on a harvest site and describe the situation where they are appropriately used.
- The viewing of ecosystems where the goal at each site is to assess the whole area while addressing questions on the various components you are asked to observe and understand.
- To understand the importance and benefits of trees in the urban habitat for a wide variety of reasons, including wildlife habitat, windbreaks, energy conservation, shade benefits, erosion control, aesthetics and others. To understand proper care of trees in the urban environment.
- Trees and forests occur in certain locations for certain reasons that are often identifiable by observing the site and the larger area surrounding the site. These may be as simple as the soil type, the amount of soil moisture, or need for a park or natural area within a residential area.
- Highly productive soils are often used for agricultural production and would also support a highly productive forest. As sites become less acceptable for agriculture due to drought or wet soils, certain tree species and forest types can still maintain high levels of productivity on many of these sites.
- As the amount of soil moisture on a site increases, there is a change in the types of vegetation that become dominant. Wetland sites have special combinations of tree species, shrubs, and herbaceous plants that are part of the important functions these sites contribute to the environment.
- Wildlife habitat is affected by the age, size, density, variety of tree species, and location of the trees or forest stands in relation to surrounding ecosystems such as residential areas, other wooded areas, streets and water sources. The level of importance of trees is dependent upon the ecosystem (prairie, wetland, agricultural field, forest) and the wildlife being studied.
